Abstract

See full text

Method and apparatus are provided to prevent unneccessary execution of TCP/IP performance enhancing algorithms in a wireless communications network. The method includes monitoring acknowledgment message traffic between a sending unit and a receiving unit and preventing forwarding of an acknowledgment message to the sending unit when the acknowledgment message is a second duplicate acknowledgment message. The apparatus includes a first endpoint unit connected between a sending unit and a receiving unit. The first endpoint unit includes a monitor component to monitor acknowledgment message traffic between the sending unit and the receiving unit and a filter unit to prevent forwarding of a duplicate acknowledgment message to the sending unit until a predefined condition is met.
